FIG. 1 andFIG. 2 , thecamera assembly 100 according to embodiments of the present disclosure includes twolens assemblies 10. Eachlens assembly 10 includes animage sensor 12. Eachimage sensor 12 includes apixel array 122 and acontrol circuit 124. - The
pixel array 122 includes alight sensing region 1222 and animaging region 1224. Thecontrol circuit 124 is configured to control thelight sensing region 1222 to detect an illumination intensity when a light sensing instruction is received. Thecontrol circuit 124 is further configured to control theimaging region 1224 to obtain an image when an imaging instruction is received. - In some embodiments, the
lens assembly 10 further includes afilter 14. Thefilter 14 and theimaging region 1224 are arranged correspondingly. Light would reach theimaging region 1224 after passing through thefilter 14. Thefilter 14 may be anRGB filter 14. TheRGB filter 14 can be arranged in Bayer array to allow light L to pass through thefilter 14 and pass through theimaging region 1224, so as to obtain a color image. Further, in some embodiments, thelens assembly 10 may further include a visible filter. The visible filter and thelight sensing region 1222 are arranged correspondingly to allow light L to pass through the visible filter and to reach thelight sensing region 1222. In this way, after the light L passes through the visible filter, visible light of the light L can reach thelight sensing region 1222, such that thelight sensing region 1222 can detect the illumination intensity of the visible light, thus avoiding interference of invisible light such as infrared light, ultraviolet light or the like in the light L. - The
camera assembly 100 according to embodiments of the present disclosure can be applied in anelectronic device 1000 according to embodiments of the present disclosure. Theelectronic device 1000 further includes aprocessor 200. Theprocessor 200 is configured to generate the light sensing instruction and the imaging instruction. In some embodiments, theelectronic device 1000 further includes adisplay screen 300. Thedisplay screen 300 is configured to display data information such as video, image, text, icon and the like. - In the
camera assembly 100 and theelectronic device 1000 mentioned above, thecontrol circuit 124 can realize both detection of the illumination intensity and acquisition of the image by controlling thepixel array 122. In this way, it is unnecessary to set both a camera component and a light sensor component, such that the number of components is reduced, a ratio of space for locating thedisplay screen 300 can be increased, thus increasing the screen-to-body ratio of theelectronic device 1000. - In some embodiments, two
lens assemblies 10 include a main lens assembly and a secondary lens assembly. An area of the imaging region of the main lens assembly is larger than an area of the imaging region of the secondary lens assembly, such that the main lens assembly can realize a better imaging quality. Further, an area of thepixel array 122 of the main lens assembly can be the same as or be different from an area of thepixel array 122 of secondary lens assembly. - The
electronic device 1000 may be a cell phone, a tablet computer, a smart watch or the like. Theelectronic device 1000 according to embodiments of the present will be explained by taking a cell phone as an example. The illumination intensity detected by thecamera assembly 100 can be considered as the basis for adjusting display brightness of thedisplay screen 300 of theelectronic device 1000. For example, when the illumination intensity is high, the display brightness of thedisplay screen 300 can be increased. When the illumination intensity is changed from a high value to a value less than a certain threshold, it can be determined that a user is answering the phone, such that thedisplay screen 300 can be turned off. The image obtained by thecamera assembly 10 can be displayed on thedisplay screen 300, or stored in storage medium of theelectronic device 1000 for reading or transmitting. - The
camera assembly 100 together with thedisplay screen 300 can be set on afront face 400 of theelectronic device 1000. Thecamera assembly 100 can also be disposed on aback face 500 or side face of theelectronic device 1000. The twolens assemblies 10 of thecamera assembly 100 can be arranged laterally or longitudinally. - The
processor 200 is configured to generate the light sensing instruction and the imaging instruction. Further, theprocessor 200 is configured to transmit the light sensing instruction and the imaging instruction to thecontrol circuit 124. In some embodiments, theprocessor 200 can separately generate and transmit the light sensing instruction, or separately generate and transmit the imaging instruction, or simultaneously generate and transmit the light sensing instruction and the imaging instruction. The light sensing instruction and the imaging instruction can be generated by theprocessor 200 when receiving an input operation. The input operation can be an operation inputted by the user or by an application environment. For example, in the cell phone according to embodiments of the present disclosure, the light sensing instruction and the imaging instruction can be generated by theprocessor 200 after receiving an operation of touching the cell phone or pressing a certain function key (including a physical key, a virtual key) from the user. In some embodiments, the light sensing instruction and the imaging instruction can be generated by theprocessor 200 when the system time of the cell phone reaches a predetermined time point. - A
single control circuit 124 can receive the light sensing instruction and the imaging instruction simultaneously. In other words, thecontrol circuit 124 can simultaneously control thelight sensing region 1222 to detect the illumination intensity and control theimaging region 1224 to acquire the image. Certainly, thecontrol circuit 124 can also be configured to separately receive the light sensing instruction to control thelight sensing region 1222 to detect the illumination intensity, or separately receive the imaging instruction to control theimaging region 1224 to acquire the image. When thecontrol circuit 124 does not receive the light sensing instruction and the imaging instruction, thelight sensing region 1222 and theimaging region 1224 may be in the non-operating state. - The two
control circuits 124 may receive the light sensing instruction and the imaging instruction separately. Thecamera assembly 100 may generate two light sensing instructions and two imaging instructions, which may be a first light sensing instruction, a second light sensing instruction, a first imaging instruction and a second imaging instruction. The first light sensing instruction may be sent only to afirst control circuit 124, but not to asecond control circuit 124. The second light sensing instruction may be sent only to thesecond control circuit 124, but not to thefirst control circuit 124. Similarly, the first imaging instruction may be sent only to thefirst control circuit 124, but not to thesecond control circuit 124. The second imaging instruction may be sent only to thesecond control circuit 124, but not to thefirst control circuit 124. The twocontrol circuits 124 may receive the light sensing instruction and the imaging instruction simultaneously. For example, thecamera assembly 100 may generate a light sensing instruction and an imaging instruction. The light sensing instruction is sent to thefirst control circuit 124 and thesecond control circuit 124 simultaneously. In other words, one light sensing instruction may be used to control twolight sensing regions 1222 to detect the illumination intensity. Similarly, the imaging instruction is sent to thefirst control circuit 124 and the second control circuit simultaneously. In other words, one imaging instruction may be used to control twoimaging regions 1224 to acquire images. - In some embodiments, the
pixel array 122 includes a plurality of pixels arranged in an array. The pixels in thelight sensing region 1222 are configured to detect the illumination intensity. The pixels in theimaging region 1224 are configured to acquire the image. Each pixel can generate corresponding electric quantity according to the illumination intensity of light reaching the pixel. Thecontrol circuit 124 is electrically connected to each pixel. Thecontrol circuit 124 acquires the electric quantity generated by the corresponding pixel according to the received light sensing instruction or imaging instruction, and further analyzes magnitude of the electric quantity via theprocessor 200 to obtain the illumination intensity of the light reaching the corresponding pixel or further performs comprehensive analysis on the illumination intensities of light reaching several pixels via theprocessor 200 to obtain the image. - Referring
FIG. 2 again, in some embodiments, there is asingle camera assembly 100. Thesingle camera assembly 100 is configured as afront camera assembly 100 a. Whenlight sensing sensors 1222 of twoimaging sensors 12 detect a first illumination intensity and a second illumination intensity respectively, theprocessor 200 is configured to select a maximum of the first illumination intensity and the second illumination intensity as a final illumination intensity; or theprocessor 200 is configured to obtain a mean value of the first illumination intensity and the second illumination intensity as the final illumination intensity. - The
front camera assembly 100 a and thedisplay screen 300 are disposed on thefront face 400 of theelectronic device 1000. Thefront camera assembly 100 a may be configured to detect the illumination intensity on thefront face 400 and acquire the image opposite to thefront face 400 simultaneously. - In this way, the
processor 200 can obtain the final illumination intensity after perform the comprehensive analysis on the first illumination intensity and the second illumination intensity respectively obtained by twolight sensing regions 1222. Theelectronic device 1000 further performs corresponding control according to the final illumination intensity, for example adjusting the display brightness of thedisplay screen 300. In some embodiments, during the usage, there may be a situation that twolens assemblies 10 receive very different illumination intensities. For example, when the user operates theelectronic device 1000 under the shade of a tree, onelens assembly 10 may be in the shade while theother lens assembly 10 may be exposed under direct sunlight, such that there may be large difference between the first illumination intensity and the second illumination intensity detected by twolight sensing regions 1222. Theprocessor 200 processes the first illumination intensity and the second illumination intensity to obtain the final illumination intensity and adjusts the display brightness of thedisplay screen 300 according to the final illumination intensity, thus preventing the display brightness from being too high or too low. - Further, the two
lens assemblies 10 in thefront camera assembly 100 a may realize imaging simultaneously or on time-sharing. - Working or not working of each of the two
light sensing regions 1222 and the twoimaging regions 1224 in thefront camera assembly 100 a is independent of the others. The operating state of thefront camera assembly 100 a may be represented by a combination indicating whether each of the twolight sensing regions 1222 and the twoimaging regions 1224 is working or not. As illustrated in table 1, if an indication “✓” is used for alight sensing region 1222 or animaging region 1224, it means that thelight sensing region 1222 or theimaging region 1224 is working. If an indication “x” is used for alight sensing region 1222 or animaging region 1224, it means that thelight sensing region 1222 or theimaging region 1224 is not working. -

lens assemblies 10 in thefront camera assembly 100 a can realize imaging simultaneously to optimize the imaging quality. For example, the twolens assemblies 10 in thefront camera assembly 100 a can realize imaging simultaneously to obtain multiple frames of first images and multiple frames of second images. Theprocessor 200 may analyze the multiple frames of first images and the multiple frames of second images and screens out a frame of image with highest imaging quality as a final image. In another embodiment, theprocessor 200 may perform merging and splicing processing on the first image and the second image to enhance color and definition of the final image. - In another embodiment, one
lens assembly 10 in thefront camera assembly 100 a may be configured to assist theother lens assembly 10 in imaging, so as to optimize the imaging quality. For example, the onelens assembly 10 in thefront camera assembly 100 a may detect the current ambient brightness, and theprocessor 200 analyzes the ambient brightness to control exposure time of each light sensor component corresponding to each pixel in theother lens assembly 10 to obtain the image with suitable brightness. In this way, during the imaging of thecamera assembly 100, onelens assembly 10 is used to detect the ambient brightness to assist theother lens assembly 10 in imaging, such that problems that the final image is subject to overexposure or has too low brightness can be avoided, thus improving the image quality. - In a further embodiment, the two
lens assemblies 10 in thefront camera assembly 100 a may be enabled in sequence to realize imaging so as to optimize the imaging quality. For example, onelens assembly 10 in thefront camera assembly 100 a adopts a wide-angle lens, while theother lens assembly 10 adopts a telephoto lens. When thecamera assembly 100 realizes imaging, theprocessor 200 enables thelens assembly 10 using the wide-angle lens to realize imaging. If theelectronic device 1000 detects that the user takes a scaling-up operation for a preview image and theprocessor 200 derives an enlarging scale of the preview image higher than a predetermined value, theprocessor 200 immediately enables thelens assembly 10 using the telephoto lens to realize imaging. The wide-angle lens has a big field of view and a short focal length, while the telephoto lens has a small field of view and a long focal length. When the user takes the scaling-up operation for the preview image, it indicates that the user would like to take a picture of distant view, in this case, it needs to adopt the telephoto lens to get a clear picture of the distant view, thus it needs to switch thecamera assembly 100 to thelens assembly 10 using the telephoto lens to realize imaging so as to improve the definition of the image. - However, in some usage scenario of the
electronic device 1000, there may be a situation that the illumination intensities on thefront face 400 and theback face 500 of theelectronic device 1000 are different obviously. For example, the user may put the electronic device 1000 (e.g. a cell phone) on the table with thefront face 400 opposite to the table top. If the display brightness of thedisplay screen 300 is controlled only according to the illumination intensity on thefront face 400 detected by thefront camera assembly 100 a, thedisplay screen 300 may be in a non-display state or in a low-brightness-display state. When the user suddenly picks up theelectronic device 1000 for using, theelectronic device 1000 needs to awaken thedisplay screen 300 or to increase the brightness of thedisplay screen 300 in a short time. When the user frequently picks up and puts down theelectronic device 1000, theelectronic device 1000 would consume a great quantity of electricity energy for controlling the brightness of thedisplay screen 300. For another example, if the user operates theelectronic device 1000 when he/she lies down indoor, theback face 500 may be opposite to a light source (such as a ceiling lamp) amounted on the ceiling, such that the illumination intensity on theback face 500 may be greater than that on thefront face 400. In this case, if the brightness of thedisplay screen 300 is adjusted only according to the illumination intensity on thefront face 400, it is possible that the user cannot make out the displayed content due to the low brightness. Thus, if theprocessor 200 can process both the illumination intensity on thefront face 400 and the illumination intensity on theback face 500 of theelectronic device 1000, an optimum illumination intensity can be obtained. - Referring to
FIG. 3 , in some embodiments, there is a plurality ofcamera assemblies 100. One of them is configured as afront camera assembly 100 a, a further of them is configured as arear camera assembly 100 b. Thefront camera assembly 100 a and thedisplay screen 300 are disposed on thefront face 400 of theelectronic device 1000. Thefront camera assembly 100 a may be configured to detect the illumination intensity on thefront face 400 and acquire the image opposite to thefront face 400 simultaneously. Therear camera assembly 100 b is disposed on theback face 500 of theelectronic device 1000. Therear camera assembly 100 b may be configured to detect the illumination intensity on theback face 500 and acquire the image opposite to theback face 500 simultaneously. - Working or not working of each of four
light sensing regions 1222 and fourimaging regions 1224 in thefront camera assembly 100 a and therear camera assembly 100 b is independent of the others. The operating state of thefront camera assembly 100 a may be represented by a combination indicating whether each of thelight sensing regions 1222 andimaging regions 1224 in thefront camera assembly 100 a is working or not. The operating state of therear camera assembly 100 b may be represented by a combination indicating whether each of thelight sensing regions 1222 andimaging regions 1224 in therear camera assembly 100 b is working or not. As illustrated in table 2, if an indication “✓” is used for alight sensing region 1222 or animaging region 1224, it means that thelight sensing region 1222 or theimaging region 1224 is working. If an indication “x” is used for alight sensing region 1222 or animaging region 1224, it means that thelight sensing region 1222 or theimaging region 1224 is not working. However, the operating state of thefront camera assembly 100 a and the operating state of therear camera assembly 100 b are not limited in the following table, there may be other operating states, which are not listed herein. -

light sensing regions 1222 in thefront camera assembly 100 a detect a first illumination intensity and a second illumination intensity respectively, and twolight sensing regions 1222 in therear camera assembly 100 b detect a third illumination intensity and a fourth illumination intensity respectively. In this case, the final illumination intensity of theelectronic device 1000 can be calculated based on one of the following four ways. - Way one, the
processor 200 may be configured to select a maximum of the first illumination intensity, the second illumination intensity, the third illumination intensity and the fourth illumination intensity as the final illumination intensity. - Way two, the
processor 200 may be configured to obtain a mean value of the first illumination intensity and the second illumination intensity as a front illumination intensity (the front illumination intensity refers to an illumination intensity detected by the light sensing region in the front camera assembly), to obtain a mean value of the third illumination intensity and the fourth illumination intensity as a rear illumination intensity (the rear illumination intensity refers to an illumination intensity detected by the light sensing region in the rear camera assembly), and to select a maximum of the front illumination intensity and the rear illumination intensity as the final illumination intensity. - Way three, the
processor 200 may be configured to select a maximum of the first illumination intensity and the second illumination intensity as the front illumination intensity, to obtain a mean value of the third illumination intensity and the fourth illumination intensity as the rear illumination intensity, and to select a maximum of the front illumination intensity and the rear illumination intensity as the final illumination intensity. - Way four, the
processor 200 may be configured to obtain a mean value of the first illumination intensity and the second illumination intensity as the front illumination intensity, to select a maximum of the third illumination intensity and the fourth illumination intensity as the rear illumination intensity, and to select a maximum of the front illumination intensity and the rear illumination intensity as the final illumination intensity. - In some embodiments, the
processor 200 can switch the calculation way among the above four ways, which can be realized by the user manually or automatically according to specific values of the illumination intensities. For example, when each of the first illumination intensity, the second illumination intensity, the third illumination intensity and the fourth illumination intensity is less than a predetermined illumination intensity threshold, it may be determined that the user may use theelectronic device 1000 in a dark environment, thus theprocessor 200 can switch the calculation way to way one, i.e., selecting the maximum as the final illumination intensity. - To this, all of the four
light sensing regions 1222 in thefront camera assembly 100 a and therear camera assembly 100 b are configured to detect illumination intensities, and the final illumination intensity obtained by theprocessor 200 can reflect the actual illumination intensity of the environment objectively. - In some operating states, for example, in the operating state No. 4 of table 2, one
light sensing region 1222 in thefront camera assembly 100 a detects a first illumination intensity, onelight sensing region 1222 in therear camera assembly 100 b detects a second illumination intensity. Theprocessor 200 is configured to select a maximum of the first illumination intensity and the second illumination intensity as the final illumination intensity. - To this, each of the
front camera assembly 100 a and therear camera assembly 100 b enables onelight sensing region 1222 when working to save energy. When onelight sensing region 1222 in thefront camera assembly 100 a breaks down, the otherlight sensing region 1222 in thefront camera assembly 100 a can be used to detect the first illumination intensity. When onelight sensing region 1222 in therear camera assembly 100 b breaks down, the otherlight sensing region 1222 in therear camera assembly 100 b can be used to detect the second illumination intensity. Thus, the normal use of theelectronic device 1000 will be not affected. - In some operating states, for example, in the operating state No. 2 of table 2, two
light sensing regions 1222 in thefront camera assembly 100 a detect a first illumination intensity and a second illumination intensity respectively, and onelight sensing region 1222 in therear camera assembly 100 b detects a third illumination intensity. In this way, the final illumination intensity of theelectronic device 1000 can be calculated based on one of the following two ways. - Way one, the
processor 200 is configured to select a maximum of the first illumination intensity and the second illumination intensity as the front illumination intensity, and to select a maximum of the front illumination intensity and the third illumination intensity as the final illumination intensity. - Way two, the
processor 200 is configured to obtain a mean value of the first illumination intensity and the second illumination intensity as the front illumination intensity, and to select a maximum of the front illumination intensity and the third illumination intensity as the final illumination intensity. - In some embodiments, the
processor 200 can switch the calculation way between the above two ways. Therear camera assembly 100 b only enables onelight sensing region 1222 when working, to save energy. When onelight sensing region 1222 in therear camera assembly 100 b breaks down, the otherlight sensing region 1222 in therear camera assembly 100 b can be used to detect the third illumination intensity. Thus, the normal use of theelectronic device 1000 will be not affected. - In some operating states, for example, in the operating state No. 3 of table 2, one
light sensing region 1222 in thefront camera assembly 100 a detects a first illumination intensity, and twolight sensing regions 1222 in therear camera assembly 100 b detect a second illumination intensity and a third illumination intensity respectively. In this way, the final illumination intensity of theelectronic device 1000 can be calculated based on one of the following two ways. - Way one, the
processor 200 is configured to select a maximum of the second illumination intensity and the third illumination intensity as the rear illumination intensity, and to select a maximum of the rear illumination intensity and the first illumination intensity as the final illumination intensity. - Way two, the
processor 200 is configured to obtain a mean value of the second illumination intensity and the third illumination intensity as the rear illumination intensity, and to select a maximum of the rear illumination intensity and the first illumination intensity as the final illumination intensity. - In some embodiments, the
processor 200 can switch the calculation way between the above two ways. Thefront camera assembly 100 a only enables onelight sensing region 1222 when working, to save energy. When onelight sensing region 1222 in thefront camera assembly 100 a breaks down, the otherlight sensing region 1222 in thefront camera assembly 100 a can be used to detect the first illumination intensity. Thus, the normal use of theelectronic device 1000 will be not affected. - Further, the
front camera assembly 100 a and therear camera assembly 100 b can realize imaging simultaneously or on time-sharing. - In one embodiment, the
front camera assembly 100 a and therear camera assembly 100 b can realize imaging simultaneously. For example, theprocessor 200 enables both thefront camera assembly 100 a and therear camera assembly 100 b. Therear camera assembly 100 b is configured to take a picture of the scenery behind theelectronic device 1000. Thefront camera assembly 100 a is configured to take a picture of face of the user. Thedisplay screen 300 of theelectronic device 1000 displays the images captured by both thefront camera assembly 100 a and therear camera assembly 100 b simultaneously. Further, theprocessor 200 may store the images captured at the same time by both thefront camera assembly 100 a and therear camera assembly 100 b in association with each other. When the user browses the stored images, both the scenery and the face of the user who enjoys the scenery can be checked, thus improving the user experience. - In another embodiment, the
front camera assembly 100 a and therear camera assembly 100 b may realize imaging on time-sharing. For example, thefront camera assembly 100 a is working while therear camera assembly 100 b is disabled, or thefront camera assembly 100 a is disabled but therear camera assembly 100 b is working. In this way, theelectronic device 1000 not only can take a picture of the scenery behind theelectronic device 1000 but also can capture the selfie. - The two
lens assemblies 10 in thefront camera assembly 100 a may realize imaging simultaneously or on time-sharing to optimize the imaging quality. The twolens assemblies 10 in therear camera assembly 100 b may also realize imaging simultaneously or on time-sharing to optimize the imaging quality, which will not be described herein. - Referring to
FIGS. 4-6 , in some embodiments, theelectronic device 1000 further includes adifferent camera assembly 600. Thedifferent camera assembly 600 includes animage sensor 30. Theimage sensor 30 includes apixel array 32 and acontrol circuit 34. Thepixel array 30 includes alight sensing region 322 and animaging region 324. Thecontrol circuit 34 is configured to control thelight sensing region 322 to detect an illumination intensity when a light sensing instruction is received, and to control theimaging region 324 to acquire an image when an imaging instruction is received. - Referring to
FIG. 5 , in some embodiments, there is asingle camera assembly 100 configured as thefront camera assembly 100 a. Thedifferent camera assembly 600 is configured as therear camera assembly 600 b. - Referring to
FIG. 6 , in some embodiments, there is asingle camera assembly 100 configured as therear camera assembly 100 b. Thedifferent camera assembly 600 is configured as thefront camera assembly 600 a. - The
processor 200 can perform comprehensive processing on the illumination intensities detected by thedifferent camera assembly 600 and thecamera assembly 100 and the acquired images to acquire a final illumination intensity and a final image. The processing ways may be similar to those used by theprocessor 200 to acquire the final illumination intensity and the final image according to the illumination intensities detected by twocamera assemblies 100 and the images acquired by the twocamera assemblies 100, which will not be described herein. - In some embodiments, a ratio of an area of the
imaging region 1224 to an area of thepixel array 122 is greater than or equal to 0.6, and/or a ratio of an area oflight sensing region 1222 to the area of thepixel array 122 is greater than or equal to 0.1. In some embodiments, the ratio of the area of theimaging region 1224 to the area oftie pixel array 122 may be 0.6, 0.7, 0.77, 0.8, 0.9 or the like. The ratio of the area oflight sensing region 1222 to the area of thepixel array 122 may be 0.1, 0.2, 0.22, 0.4 or the like. Accordingly, it ensures that theimage sensor 12 has a better imaging effect on the basis of having the function of detecting the illumination intensity. - In some embodiments, the two
pixel arrays 122 of the twolens assemblies 10 may be the same, or may not be the same. - Referring to
FIGS. 7 and 8 , in some embodiments, theimaging region 1224 is contiguous and located in the middle of thepixel array 122. Thelight sensing region 1222 is located around theimaging region 1224. Thus, it is easy for thecontiguous imaging region 1224 to generate a continuous and complete image. In some embodiments, the center of theimaging region 1224 and the center of thepixel array 122 may coincide. Theimaging region 1224 may adopt a central symmetry structure. Thelight sensing region 1222 may be located at one or more sides of theimaging region 1224. - In some embodiments, the
light sensing region 1222 may include a plurality oflight sensing sub-regions 1225 having the same area and spaced from each other. - The illumination intensity detected by the
light sensing region 1222 may be obtained by taking illumination intensities detected by all the pixel points in thelight sensing region 1222 into account. Thus, in order to obtain an objective illumination intensity, thelight sensing region 1222 is decentralized as much as possible. In other words, thelight sensing region 1222 is decentralized as a plurality of spacedlight sensing sub-regions 1225. - The plurality of
light sensing sub-regions 1225 spaced from each other may extend a detection range of thelight sensing region 1222 and may improve an accuracy of detection of thelight sensing region 1222. In an embodiment, there are fourlight sensing sub-regions 1225. Thelight sensing sub-regions 1225 may have a same area. The plurality oflight sensing sub-regions 1225 may be arranged above, under, on the left, right of theimaging region 1224 respectively. The number and positions of the plurality of light sensing sub-regions are not limited herein. - Referring to
FIG. 9 , in some embodiments, the plurality oflight sensing sub-regions 1225 include a leftlight sensing sub-region 1226 and a rightlight sensing sub-region 1227. The leftlight sensing sub-region 1226 is on the left of theimaging region 1224, and the rightlight sensing sub-region 1227 is on the right of theimaging region 1224. The leftlight sensing sub-region 1226 and the rightlight sensing sub-region 1227 are arranged symmetrically. The leftlight sensing sub-region 1226 detects a left illumination intensity (the left illumination intensity refers to an illumination intensity detected by the left light sensing sub-region). The rightlight sensing sub-region 1227 detects a right illumination intensity (the right illumination intensity refers to an illumination intensity detected by the right light sensing sub-region). The illumination intensity detected by thelight sensing region 122 is a mean value of the left illumination intensity and the right illumination intensity. - To this, influences of the left
light sensing sub-region 1226 and the rightlight sensing sub-region 1227 to the illumination intensity detected by thelight sensing region 122 are the same essentially, thus the problem that the detection result is inaccurate because thelight sensing region 122 is too sensitive to light change on the left or right of the imaging region can be avoided. - In some embodiments, the plurality of
light sensing sub-regions 1225 include an upperlight sensing sub-region 1228 and a lowerlight sensing sub-region 1229. Theupper sensing sub-region 1228 is above theimaging region 1224. The lowerlight sensing sub-region 1229 is under theimaging region 1224. The upperlight sensing sub-region 1228 and the lowerlight sensing sub-region 1229 are arranged symmetrically. The upperlight sensing sub-region 1228 detects an upper illumination intensity (the upper illumination intensity refers to an illumination intensity detected by the upper light sensing sub-region). The lowerlight sensing sub-region 1229 detects a lower illumination intensity (the lower illumination intensity refers to an illumination intensity detected by the lower light sensing sub-region). The illumination intensity detected by thelight sensing region 122 is a mean value of the upper illumination intensity and the lower illumination intensity. - To this, influences of the upper
light sensing sub-region 1228 and the lowerlight sensing sub-region 1229 to the illumination intensity detected by thelight sensing region 122 are the same essentially, thus the problem that the detection result is inaccurate because thelight sensing region 122 is too sensitive to light change above or under the imaging region can be avoided. - In some embodiments, the plurality of
light sensing sub-regions 1225 include a leftlight sensing sub-region 1226, a rightlight sensing sub-region 1227, an upperlight sensing sub-region 1228 and a lowerlight sensing sub-region 1229. The leftlight sensing sub-region 1226 and the rightlight sensing sub-region 1227 are arranged symmetrically, and the upperlight sensing sub-region 1228 and the lowerlight sensing sub-region 1229 are arranged symmetrically. In an embodiment, the leftlight sensing sub-region 1226, the rightlight sensing sub-region 1227, the upperlight sensing sub-region 1228 and the lowerlight sensing sub-region 1229 are centrally symmetric. The leftlight sensing sub-region 1226 detects a left illumination intensity. The rightlight sensing sub-region 1227 detects a right illumination intensity. The upperlight sensing sub-region 1228 detects an upper illumination intensity. The lowerlight sensing sub-region 1229 detects a lower illumination intensity. The illumination intensity detected by thelight sensing region 122 is a mean value of the left illumination intensity, the right illumination intensity, the upper illumination intensity and the lower illumination intensity. - To this, influences of the left
light sensing sub-region 1226, the rightlight sensing sub-region 1227, the upperlight sensing sub-region 1228 and the lowerlight sensing sub-region 1229 to the illumination intensity detected by thelight sensing region 122 are the same essentially, thus the problem that the detection result is inaccurate because thelight sensing region 122 is too sensitive to light change above, under, on the left or right of the imaging region can be avoided. - The sub-regions being arranged symmetrically means that the sub-regions are symmetric in area and shape with regard to the
imaging region 1224. - Referring to
FIGS. 10 and 11 , in some embodiments, thepixel array 122 is in a shape of a circle or an ellipse. Theimaging region 1224 is in a shape of an inscribed rectangle of thepixel array 122. Thelight sensing region 1222 includes a region other than the inscribed rectangle of the circle or the ellipse. - Accordingly, the
imaging region 1224 is in the middle of thepixel array 122, which can acquire the image easily. Thelight sensing region 1222 is decentralized. Thelight sensing region 1222 on the left of theimaging region 1224 and thelight sensing region 1222 on the right of theimaging region 1224 are symmetric. Thelight sensing region 1222 has the same sensitivity to light change on the left and right of theimaging region 1224. Thelight sensing region 1222 above theimaging region 1224 and thelight sensing region 1222 under theimaging region 1224 are symmetric. Thelight sensing region 1222 has the same sensitivity to light change above and under theimaging region 1224. Thus, thelight sensing region 1222 can obtain an accurate detection result. - Referring to
FIGS. 12 and 13 , the pixel array is in a shape of rectangle. Theimaging region 1224 is in a shape of an inscribed circle or an inscribed ellipse of the rectangle. Thelight sensing region 1222 includes a region other than the inscribed circle or the inscribed ellipse of the rectangle. - Accordingly, the
imaging region 1224 is in the shape of the circle or ellipse. The user can obtain an image in the shape of circle or ellipse via theimaging region 1224 without further post-processing, thus satisfying the user's personalized demand. Thelight sensing region 1222 is decentralized, such that the accuracy of the illumination intensity detected by thelight sensing region 1222 can be improved. - Thus, the
imaging region 1224 is in the middle of thepixel array 122, which can acquire the image easily. Thelight sensing region 1222 above theimaging region 1224 and thelight sensing region 1222 under theimaging region 1224 are symmetric. Thelight sensing region 1222 on the left of theimaging region 1224 and thelight sensing region 1222 on the right of theimaging region 1224 are symmetric. - Referring to
FIGS. 14 and 15 , in some embodiments, theimaging region 1224 is contiguous and thelight sensing region 1222 is contiguous. Theimaging region 1224 and thelight sensing region 1222 share a common boundary. Twoimaging regions 1224 of the twolens assemblies 10 are located between twolight sensing regions 1222 of the twolens assemblies 10. Thus, thepixel array 122 has a simple structure. Thecontrol circuit 124 may easily find the pixels in the correspondingimaging region 1224 or the correspondinglight sensing region 1222 after receiving the light sensing instruction or the imaging instruction. In some embodiments, the ratio of the area of theimaging region 1224 to the area of thepixel array 122 is 0.8. The ratio of the area of thelight sensing region 1222 to the area of thepixel array 122 is 0.2. Theimaging region 1224 may be in the shape of a rectangle, such that theimaging region 124 may obtain an image in the shape of the rectangle. Thelight sensing region 1222 may also be in the shape of a rectangle, and a long edge of thelight sensing region 1222 may intersect a long edge of theimaging region 1224 or a short edge of theimaging region 1224. - Two
imaging regions 1224 of the twolens assemblies 10 are arranged between twolight sensing regions 1222 of the twolens assemblies 10. In some embodiments, as illustrated inFIG. 14 , when the twolens assemblies 10 are arranged laterally, onelight sensing region 1222 is arranged on the left of aleft image sensor 12 and the otherlight sensing region 1222 is arranged on the right of aright image sensor 12. As illustrated inFIG. 15 , when the twolens assemblies 10 are arranged longitudinally, onelight sensing region 1222 is arranged above anupper image sensor 12 and the otherlight sensing region 1222 is arranged under alower image sensor 12. In this way, the twolight sensing regions 1222 of thecamera assembly 10 can detect in wide range and obtain more accurate detection result. - The arrangement of the
